As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

I think, like you said, due to the fact that there's a larger space when it comes to the hotel lobbies is the reason as to why it works. I think that no matter what you put on the walls (whether it be concrete or marble) will result in tiles not working out. The industrial look tends to be exposed brickwork anyway, or cream or white colours so maybe that's an option you could look into. What did you end up doing?

wow, what a transformation

I'll start with what I personally don't like , but obviously some people do -- The two couches look like they match ( which is good ) and in a green leather ( again good ) , but the browny olive carpet doesn't really work . Than you have a green fabric rolled arm chair , that is 100 years old in design and fabric design -- just because it is green , doesn't mean it works with the couches , because it doesn't . The chair that does tie in ( the green leather one ) is in a funny spot , but I also think it would look funny between the 2 couches . Then you have a nice armchair 'up the top' , and I think/hope that the fabric matches the dining chairs ? Then the TV area looks 'busy' . Probably the least of your worries , just an observation . SO -- I'd move the rolled arm chair right out of the room . The couch along the window I'd move around to beside the other one , and then the single green leather around by the window , so you have a green leather semi-circle . Personally , I still don't like the leather and the the carpet 'clash' , so I'd like to change the carpet ( or the lounge suite if you are wanting a change there -- although you'd have to go maybe that 'shooting lounge' aged brown leather if you want to keep the carpet ? ) . 'Up the top' by the bookcases I'd try and get a second chair the same as the other wheat/grey one , and add a coffee table -- so you have a conversation area , and a lower lounge/TV area . If it was me , I'd probably remove and wall in the 2 'left-hand' side windows -- the one that the blind is closed and I suspect is closed most of the time , and the one behind the TV . I'd then wall mount the TV ( if done professionally , you get the power and aerial all hidden ) so it cleans up that area , but that does start getting costier .
